Embodiment 1

[0036] In view of the above problems, this embodiment provides a nursing device for assisting blood purification. The device has a unique structure and is easy to use. It can not only effectively solve the problem that manual pressing of the needle eye to stop bleeding after the existing blood purification is easy to produce a feeling of pressing fatigue, and congestion is prone to occur. It also effectively solves the problem that it is difficult for the pressing personnel to control the pressing force of the hand when the patient is moving.

[0037] like Figure 1-12 As shown, the nursing device for assisting blood purification provided in this embodiment includes a fixing unit and a pressure applying unit. The pressure applying unit includes a diamond-shaped sealing chamber 1, a diamond-shaped inner frame 2, a pressure regulating assembly 3 and a pressure plate 4. The inner frame 2 is concentrically arranged in the rhombus-shaped sealing chamber 1, the four top corners of t...

Embodiment 2

[0049] like Figure 13As shown, the bottom of the pressure plate is provided with double-sided adhesive tape 43, the hemostatic cotton is fixed on the bottom surface of the pressure plate by using the double-sided adhesive tape, and the upper end surface of the hemostatic cotton is provided with an impermeable membrane, so that the blood stains on the hemostatic cotton will not be contaminated when in use. Contaminate the platen on the double-sided tape to facilitate disinfection of the platen.

Embodiment 3

[0051] In view of the above problems, the difference between the device provided in this embodiment and the device provided in Embodiment 2 is that a delay recovery component is provided in the diamond-shaped inner frame, such as Figure 14 As shown, the delay recovery device includes a connecting rod 81 arranged symmetrically along the horizontal diagonal line, the distal end of the connecting rod 81 is fixedly connected with the inner apex angle of the adjacent side diamond-shaped inner frame 2, and the distal end of the connecting rod 81 is arranged oppositely, A retarding magnet 82 is fixed, and the magnetic poles of the adjacent ends of the two retarding magnets 82 are opposite to each other, so that when the two vertices of the horizontal diagonal line of the diamond-shaped outer frame are manually squeezed to deform, the two retarding magnets 82 in the inner diamond-shaped frame will be deformed. Gradually approaching, and because the magnetic poles of the adjacent ends ...

Abstract

The invention discloses a nursing device for assisting blood purification, which comprises a fixing unit and a pressure applying unit, the pressure applying unit comprises a rhombic sealing chamber, a rhombic inner frame, a pressure regulating assembly and a pressure plate, the rhombic inner frame is concentrically arranged in the rhombic sealing chamber, and the pressure regulating assembly is arranged in the rhombic sealing chamber; the upper, lower, left and right top corners of the rhombic sealing chamber and the four top corners of the inner frame are hinged ends, and the closed-loop end faces of the front section and the rear section of the inner frame are connected with the inner wall of the rectangular sealing chamber on the adjacent side, so that the rhombic sealing chamber is hermetically divided into an outer annular chamber and an inner adjusting chamber; the device is unique in structure and convenient to use, not only can effectively solve the problem that pressing fatigue is easily generated and effective pressing is difficult to keep when a needle eye is manually pressed for hemostasis after existing blood purification, but also effectively solves the problem that a pressing person is difficult to control the hand pressing force when a patient moves.

Description

technical field [0001] The invention belongs to the technical field of blood purification appliances, and in particular relates to a nursing device for assisting blood purification. Background technique [0002] Blood purification is also called dialysis in daily life. Its meaning is: the patient's blood is drawn out of the body and passed through a purification device to remove some of the pathogenic substances, purify the blood, and achieve the purpose of curing diseases. Blood purification should include: hemodialysis, hemofiltration, hemoperfusion, plasma exchange, immunoadsorption, etc. [0003] Before blood purification, it is necessary to prepare vascular access. The purpose is to drain the blood from the body on the dialysis machine for detoxification and drainage. The way to prepare the vascular access is to perform fistula surgery during dialysis, that is, connect the arteries and veins of the upper limbs together To make a fistula, the blood flow rate in the vei...
